Psalm to combat fear

When you are afraid remember Psalm 27

1.The Lord is my light and my salvation—
whom shall I fear?
The Lord is the stronghold of my life—
of whom shall I be afraid?
2 When the wicked advance against me
to devour[a] me,
it is my enemies and my foes
who will stumble and fall.
3 Though an army besiege me,
my heart will not fear;
though war break out against me,
even then I will be confident.
4 One thing I ask from the Lord,
this only do I seek:
that I may dwell in the house of the Lord
all the days of my life,
to gaze on the beauty of the Lord
and to seek him in his temple.
5 For in the day of trouble
he will keep me safe in his dwelling;
he will hide me in the shelter of his sacred tent
and set me high upon a rock.
